		                        			Paint contains various complex chemical mixtures, such as aliphatic hydrocarbons, aromatic hydrocarbons (primarily toluene), ketones, and benzene as reported at previous studies. Toxicity from some chemicals can cause early 
DNA damage with various factors. A scoping review was conducted via literature review on relevant studies on the 
effect of paint exposure on paint workers and DNA damage. A systematic search was conducted in October 2021 
via PubMed, Scopus, and Web of Science databases. The key terms used were paint, solvent-based paint, organic 
solvent, mixed organic solvent, occupational exposure and DNA damage, oxidative stress, genotoxicity on a painter, 
paint worker. From 561 articles, only 13 articles were finally selected based on the inclusion, exclusion criteria, and 
eligibility criteria. The literature showed that biomonitoring studies on painters were consistently reporting positive 
and significant DNA damage due to exposure to different types of compounds mixed in a paint. However, there were 
fewer studies on paint manufacturing factory workers compared to painters while paint manufacturing workers exposed various chemical everyday during the paint production which potentially susceptible to occupational toxicity. 
In conclusion, this review suggests that exposure to paints could induce early DNA damage among paint workers 
and further investigations on paint exposure among paint manufacturing factory workers and the DNA damage were 
needed in order to improve occupational health among paint workers in the future.

		                        			INTRODUCTION:
		                        			Lifestyle activities, such as regular physical activity, are important for good metabolic health and the prevention of non-communicable diseases. Epidemiological studies highlight an increase in the proportion of overweight children in Singapore. A workgroup was formed to develop recommendations to encourage children and adolescents (aged 7-17 years) to adopt a holistic approach towards integrating beneficial activities within a daily 24-hour period for good metabolic and general health.
		                        		
		                        			METHODS:
		                        			The Grading of Recommendations Assessment, Development and Evaluation (GRADE) Evidence to Decision framework was employed to formulate the public health question, assess the evidence and draw conclusions for the guide. The evidence for international 24-hour movement guidelines, and guidelines for physical activity, sedentary behaviour, and sleep and eating habits were reviewed. An update of the literature review from August 2018 to end of September 2020 was conducted through an electronic search of Medline and Cumulative Index to Nursing and Allied Health Literature (CINAHL) databases.
		                        		
		                        			RESULTS:
		                        			Ten consensus statements were developed. The statements focused on the overall aim of achieving good metabolic health through integration of these activities and initiatives: light and moderate- to vigorous-intensity physical activity on a regular basis; muscle- and bone-strengthening activities; limiting sedentary behaviour; regular and adequate sleep; good eating habits and choosing nutritionally balanced foods and drinks; practise safety in exercise; and aiming to achieve more or all aforementioned recommendations for the best results.
		                        		
		                        			CONCLUSION
		                        			This set of recommendations provides guidance to encourage Singapore children and adolescents to adopt health-beneficial activities within a 24-hour period.

		                        			Anomalous Aortic Origin of a Coronary Artery (AAOCA) is a
rare anomaly of the coronary artery with a considerable risk
of sudden cardiac death due to ischaemia of the heart.
Symptoms may include chest pain on exertion,
breathlessness or dizziness. We encountered a case of a 46-
year-old female who complained of exertional chest pain
with a positive-stress test and subsequently diagnosed with
AAOCA through CT angiography (CTA). She successfully
underwent a coronary artery bypass graft (CABG) surgery
using a saphenous vein graft with uneventful recovery. Right
internal mammary artery (RIMA) was not used as it was
flimsy and the flow was very poor.

		                        			Clinacanthus nutans (C. nutans) leaf extracts have been widely used by cancer patients in Malaysia and local practiceclaims a cure to cancer. There were several studies done to determine the cytotoxicity potency of C. nutans extracts onvarious types of cells. However, there is still lacking on the knowledge regarding the combination effect of C. nutanswith anticancer drugs. Thus, the study was carried out to determine the cytotoxicity potency of C. nutans extracts andpaclitaxel (PTX) alone and, in combination on MDA-MB-231 cells. The cells were treated with 100% ethanol extract ofC. nutans (CNE) and water extract of C. nutans (CNA), PTX and combination of both extracts and PTX for 72 hours andthe cytotoxic activity was determined using SRB assay. Result showed that CNE had little cytotoxic activity, whereas CNAshowed no cytotoxic activity on MDA-MB-231 cells. For combination treatment of C. nutans extracts and PTX, only CNEshowed significant enhanced PTX-induced cytotoxicity (p < 0.05), meanwhile CNA inhibited PTX-induced cytotoxicitysignificantly (p < 0.05). As a conclusion, CNE was able to increase PTX potency to inhibit the viability of MDA-MB-231cells.

		                        			Seaweed contains various nutrients that has the potential to be a source of nutritious food, but only a few studies done on
the red seaweeds in Malaysia. Therefore, this study was conducted to determine the macronutrients content, amino acid
profile and fatty acid component in Kappaphycus alvarezii and Kappaphycus striatum. The study found that the range
of moisture, fat, ash, protein, fiber and carbohydrates content for both red seaweeds were 6.9% - 7.3%, 0.5% - 2.6%,
29.4% - 30.9%, 2.5% - 5.7% , 5.3% - 5.5% and 50.1% - 53.3% respectively. A total of 16 amino acids were identified
in which the essential amino acid for K. alvarezii and K. striatum were 41.11% and 36.15% respectively. A total of 34
fatty acids were identified in which the content of saturated fatty acids (SFA) was the highest (42.7% - 72.8%), followed
by mono-unsaturated fatty acid (MUFA) (13.8% - 36.2%) and polyunsaturated fatty acids (PUFAs) was the lowest (13.5%
- 21.2%). In conclusion, this study suggest that K. alvarezii and K. striatum are potentially be used as raw materials or
food ingredients to improve the nutritional value of the human diet.

		                        			Apart from clinical, histological and biochemical indices, genomics are now being employed to unravel the pathogenetic mechanisms in the disease progression of IgA nephritis (IgAN). The results of angiotensin converting enzyme (ACE) gene polymorphism have been controversial. Those patients with the DD genotype seem to have a poorer prognosis. However, with high dose angiotensin receptor blocker (ARB) therapy, the ACE gene polymorphism status of a patient may no longer be a matter for concern as those with the DD genotype would also respond favourably to high dose ARB therapy. Association studies with gene sequencing and haplotypes have suggested that multiple genes are involved in the pathogenesis of IgAN. Some workers have reported a synergistic effect in the combined analysis of AGT-M235T and ACE I/D polymorphism. With the use of deoxyribo nucleic acid (DNA) microarray, tens of thousands of gene expressions genome-wide can be examined together simultaneously. A locus of familial IgAN has been described with strong evidence of linkage to IgAN1 on chromosome 6q22-23. Two other loci were reported at 4q26-31 and 17q12-22. DNA microarray techniques could also help in the identification of specific pathogenic genes that are up- or down-regulated and this may allow genome wide analyses of these genes and their role in the pathogenesis and progression of IgAN. Recently, using genome-wide association studies (GWAS) more loci for disease susceptibility for IgAN have been identified at 17p13, 8p23, 22q12, 1q32 and 6p21.
